I don't think it's weird ... I collect (very slowly) nativity scenes .... but my catchi is, I only collect the ones that are all in 1 piece (or separate pieces that are permanently attached to each other) .... like ornaments, snowglobes, and such that have a nativity scene on them.

On a side note ... I'm in the middle of getting ready to move next week to a new apartment, so I'm much more involved in getting rid of stuff then in acquiring!
